Primary Irritation Patch Testis performed to evaluate the primary skin irritation that can range from none,mild, moderate to severe irritation. This results from reversible inflammatorychanges in the skin following the application of a test substance depending onthe irritation potential of the product. Based on the severity of irritationcaused due to the interaction of ingredients or composition of the testsubstance with the skin can cause perceivable sensations or symptoms. On thebasis of this, the possible hazards likely to arise from exposure of the skinto the test substance can be assessed. To know the safety or possible irritantpotential of these products, it should be tested in small group of humansbefore release of the product in market. This allows to measure and evaluatethe probable inflammatory response to an irritant which occurs only at the siteof exposure. The response tends to be universal (produces a reaction in mostindividuals) and depends on the strength and duration of exposure.
